SASH-HOLDER.

SPECIFICATION formingpart of Letters Patent No. 280,445, dated July 3, 1883.

Application filed October 4, 1882.

To all whom it may concern:

Be it known that I, RUssEL B. CALLAHAN, of Lansing, in the county of Ingham and State of Michigan, have invented new and useful Improvements in Window-Fasteners; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

The nature of this invention relates to certain new and useful improvements in the construction of window stops ,or looks of that class employed for securing the window and preventing its being raised or lowered, as may be desired; and the invention consists of the peculiar cam-wheels eccentrically pivoted by the same screw or bolt to the window-frame, operating together or separately, all as more fully hereinafter set forth.

. Figure 1 is a perspective view of a section of window and frame with my improved de vice attached thereto and adjusted to hold the window in a raised or open position. Fig. 2 is an elevation with the device ad- 2 5 justed so as to hold the window in a closed position. Fig. 3 is an elevation of the device with both cams brought into action.

In the accompanying drawings, which form a part of this specification, A represents a section of a window-sash, and B a section of the frame thereof.

0 represents my improved lock, which consists of two eccentrically-weighted disks or wheels, to b, which are designed to be eccentrically pivoted to the window-frame by means of a proper screw, 0. The under disk, a, is provided with the stop 0, and the outer disk, I), is formed with a curved opening through, which the stop 0 projects. It is further provided with the bridge f, through which passes the supporting-screw, and against which the stop 6 of the under disk rests when it 1s designed to use the disks together, their periph- (Model.

eries coinciding when the stop 6 is in contact with the bridge f. The peripheries of the disks or wheels may be roughened or covered with any proper elastic material, so that they will not mar or injure the sash.

- In practice, when it is desired to secure the window so that it cannot be raised or opened from the outside, the wheels a b are turned into the position shown in Fig. 2, with their weighted portions away from the window, which causes their peripheries to come in contact with the sash, and, upon an attempt to raise the window while in this position, the wheels operate together as a cam to firmly lock the sash. \Vhen it is desired to open the window and retain it in such opened position, the wheels or disks a b are adjusted to the position shown in Fig. 1, with their weighted portion between the fulcrum or pivotal point and the sash, when it will be found that, the wheels moving together, the window can easily be raised, while the contact between the disks and sash will prevent the latter from closing or accidentally falling down. To prevent the sash from being-raised or lowered, the disks are arranged so as to operate in opposite directions, as shown in Fig. 3.

WVhat I claim as my invention is The combination, in awindow-fastener, of the apertured disk I), provided with bridge f, with the disk a, provided with stop 6, working through the aperture in disk I), and an eccentrically-located pivot or screw, 0, whereby both disks are adapted to operate together in one direction only when the stop 6 rests over the bridge f, and singly in opposite directions when the outer disk is reversed, substantially as shown and described.
